24/0 makes them grow faster, is the reason I usually use 24/0. That's not just something I read from a book; I did the experiment to be sure, with two exactly identical cabinets. The plants really do grow significantly faster and more vigorously under 24/0 (assuming you can keep the temps under control). You can shave about a week off veg time that way, roughly.

But no, don't change now. Changing the light schedule can cause hermies. If you start 18/6, stay 18/6. If you start 24/0, stay 24/0.
jamstigator Reviewed by jamstigator on . question about light cycle I have my plants on 18/6 right now. I was wondering if it would matter if i switched them to 24/0, as i have read that in vegetative growth they do not need darkness I was thinking of adjusting the time gradually (e.g. 19/5, then 20/4, etc.) Does anyone know if this would increase my chances of hermies or males? p Rating: 5
